Generally speaking, any cable or DSL speed that is equal to or higher than 256kbps up/1.5mbps down is expected to work with cameras connected to the ADT Pulse system. If you have DSL-lite or Satellite-provided broadband connections with 128kbps up/768kbps down, you may not be able to support more than two cameras.
Other types of Internet service, such as satellite service, may not have the upstream (customer-to-Internet) bandwidth to support live video. Satellite Internet service is also subject to weather conditions in the same way that satellite TV is, and may result in the customer receiving a higher amount of ADT Pulse outage notifications.
Aircard-based wireless broadband Internet service is generally intended to be used in conjunction with a mobile device, such as a PC, and would not provide the 24/7 availability required for ADT Pulse.
Both satellite and wireless broadband Internet service are also more likely to charge fees based on usage. With services like these, you can exceed your data limit, and may receive overage charges.
